Connect External Devices with Reichert Wireless Serial Adapters
Bluetooth Dongle
Reichert designed a proprietary Bluetooth serial adapter to connect external devices to the Phoroptor
VRx. In order to establish wireless communications between the Phoroptor VRx and an external device,
you must first configure the Reichert Bluetooth dongle for a specific Central Unit port (e.g., Projector,
EMR, Instrument #1) and program the adapter with the serial communications parameters (baud rate,
data bits, parity, stop bits) required by the external device.
Perform these steps to configure a Bluetooth dongle for communication with an external device using a
specific Central Unit port:
1. Turn on the Phoroptor VRx.
2. Touch OPTIONS/SETUP MENU on the Controller screen, located at the top right of the screen.
3. Touch PORTS on the Settings screen.
4. In the Port Selection panel, select the port that you would like to congure (e.g., Instrument 1,
Instrument 2, etc).
5. On the Port Settings panel, select the device you are connecting to from the drop-down menu.
6. Set the Connection Type to Bluetooth (Dongle) for the wireless connection.
Note: if using a wired cable refer to Setting-Up a Port for Communication with an External
Device section in this manual.
7. If necessary, set the serial communication parameters to match the settings on the device you
are connecting to.
8. Provide power to the Bluetooth dongle using the power adapter provided. (Please refer to Figure
IS-13.) The LED light should illuminate green.
9. Press and hold the Bluetooth dongle’s reset switch, using an appropriate object (e.g., paperclip)
until the green LED goes out (approximately two seconds). The LED should now blink at a slow
rate (once every 2 seconds).
Note: The reset switch is accessed via the small hole located on the antenna end of the Bluetooth
dongle.
10. Connect the Bluetooth dongle to the appropriate Central Unit port, using the provided null
modem serial cable. (Please refer to Figure IS-13.)
